MASK FOR FlRElVl EN, $90.

SPECIFICATION forming part of Letters Patent No. 474,500, dated May 10, 1892.

Application filed October '7, 1891. Serial No. 408,038. (No model.)

be conveniently applied to the head, and thus protect the face, neck, and head from injury, and to be capable ofpermitting of a free action of the head of the user in `looking up or down without displacing the mask, and to provide for a temporary opening or raising of the face-protecting portion of the mask when the user is performing other than dangerous work and does not require the same, and for an easy closing of said face-protecting portion when about to perform a duty of danger.

With the above objects in View the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure l is a perspective view of a mask constructed in accordance with my invention, the same being applied in position. Fig. 2 is a perspective view of a mask in detail. Fig. 3 is aseotion of the same.

Like numerals of reference indicate like parts in all the gures of the drawings.

In forming the mask or protector I construct the same of a front face-section and a rear head-section, (designated as l and 2, respectively.) These sections each consist of a substantially inverted- U-shaped metal frame y 3, to which is connected the edges of the reticulated wire protecting-frames 4. The rear frame 3 fits Within the front frame, and the two are pivotally connected at opposite sides by means of a pair of bolts 5, passed between the two frames 3 or through the same, as may be desired, and provided upon their outer sides with disks or washers 5. The reticulated frames 4 and also the frames 3 may be of any desired strength, adapting the mask as a whole for different purposes-as, for instance, a iremans mask to preserve his head against falling brick or blazing brands would necessarily be heavier kand stronger than would either the mask of a bottler for preserving the face from being cut by the flying glass or bursting bottles or the mask of a blacksmith for preserving the face from being burned by the sparks. The frames 4 of the face and head are given a general con- Y tour, agreeing therewith, as shown, and at their lower ends are reduced to approximate the size of the neck, as indicated at 7.

S designates a sheet-metal or other band, the ends of which are perforated, as is also the middle, as indicated at 9, for the reception of the opposite bolts 5, which bolts serve as a pivotal support for the mask upon the ring, and one of said bolts has an adjustable connection between the overlapped terminals of the band. By adjusting the bolts in the perforations of the band the mask may be properly balanced thereon and the band adjusted in size to t the head of the wearer.

In applying the mask it is simply necessary to swing the lower ends of the sections apart and insert the head within the ring 8. This ring supports the mask above the head and out of contact therewith, and being pivoted to the sections permits of a raising and lowering of the head without any disarrangement of the mask, so that a bottler, blacksmith, ireman, or other person is not interfered with in his work, While at the same time his face, head, and neck are preserved against injury from blazingbrands, the glass of bursting bottles, sparks, dac.

From the above description, taken in connection with the accompanying drawings, it will be seen that I provide a mask of great simplicity and adapted to be conveniently worn by any one engaged in dangerous work, whereby a thorough protection is aorded, and that While wearing the mask the operator is not impeded in his work by reason thereof, but may freely glance up and down without danger of displacing the protector and without 9 5 IOO the maslrfrom the head, and as soon as the lated coverings 4,approxirnatingthe head and v dangerous Work is resumed the front section face of a person and reduced at their lower may be lowered. ends to form the neck 7, of t-he bolts 5, passing zo Having described my invention, what I through and pivotally connecting the sec- 5 claim istions, and the head-band 8, having the over- 1.
